Moving head light fixture with protruding diffuser cover and multiple light sources
View Patent ↗The present invention relates to a moving head light fixture comprising a base; a yoke connected rotatable to the base and a head connected rotatable to the yoke. The head comprises a number of light sources and a number of light collecting means arranged in the head, where the number of light collecting means collect and convert light from at least one of the light sources into a number of source light beams which are emitted from said head. The head comprises a diffuser cover, which comprises at least one diffuser region. The diffuser region receives and diffuses at least a part of the light and at least a part of the diffuser cover protrudes from the head. The invention relates to a illumination system comprising such a moving head and a diffuser cover protruding from the head of for a moving head light fixture.

The moving head light fixture according claim 1 wherein said number of light sources are arranged in at least a first group of light sources and in a second group of light sources, said number of light collectors collecting light from said first group of light sources and converting said collected light into a number of source light beams, wherein said diffuser region receives light generated by said second group of light sources and diffuses said received light.
6. The moving head light fixture according to claim 5 wherein said first group of light sources and said second group of light sources are independently controllable.
7. A diffuser cover for a moving head light fixture, said moving head light fixture comprises:
a base;
a yoke connected rotatably to said base;
a head connected rotatably to said yoke;
said head comprising a number of light sources and a number of light collectors arranged in said head, said number of light collectors collecting light from at least one of said light sources and converting said collected light into a number of source light beams, said source light beams being emitted from said head wherein said diffuser cover comprises at least one non-diffusing region and one diffuser region, where at least a part of said number of source light beams pass through said non-diffusing region without being diffused, and where said diffuser region receives and diffuses at least a part of said light generated by said light sources and at least a part of said diffuser cover protrudes from said head and diffuses a part of said received light sidewards and backwards in relation to the source light beams.
8. The diffuser cover according to claim 7 wherein said diffuser cover is embodied as a rigid body.
9. The diffuser cover according to claim 7 wherein at least one non-diffusing region is a clear area.
10. The diffuser cover according to claim 7 wherein at least one non-diffusing region is an aperture.
11. An illumination system comprising a central controller connected to and controlling a number of moving head light fixtures, said moving head light fixtures comprising:
a base;
a yoke connected rotatably to said base;
a head connected rotatably to said yoke;
said head comprising a number of light sources and a number of light collectors collecting means arranged in said head, said number of light collectors collecting light from at least one of said light and converting said collected light into a number of source light beams, said source light source beams being remitted from said head, wherein at least one of said moving head light fixtures comprises a head comprising a diffuser cover, said diffuser cover comprises at least one diffuser region that receives and diffuses at least a part of said light generated by said light sources, where at least a part of said diffuser cover protrudes from said head, where a plurality of said moving head light fixtures are arranged in a matrix, and where said central controller sends pixel data to said plurality of said moving head light fixtures in said matrix.
12. A moving head light fixture comprising:
a base;
a yoke connected rotatably to said base;
a head connected rotatably to said yoke;
said head comprising a number of light sources and a number of light collectors arranged in said head, said number of light collectors collecting light from at least one of said light sources and converting said collected light into a number of source light beams, said source light beams being emitted from said head, wherein said head comprises a diffuser cover, said diffuser cover comprising at least one diffuser region that receives and diffuses at least a part of said light generated by said light sources, where at least a part of said diffuser cover protrudes from said head, where said number of light sources are arranged in at least a first group of light sources and a second group of light sources, where said number of light collectors collect light from said first group of light sources and convert said collected light into a number of source light beams, and where said diffuser region receives light generated by said second group of light sources and diffuses said received light.
13. The moving head light fixture according to claim 12 wherein said first group of light sources and said second group of light sources are independently controllable.
